Ascendant basis: our Lagna follows a slightly different convention from Drik's, agreeing within about 0.3 degrees. A birth very close to a sign boundary can show a different rising sign. Planets and Panchang elements agree to under one arc-minute.
Dasha timing: our Vimshottari Dasha period boundaries agree with Drik's within a few days, not to the exact day. This comes from two documented sources: a tiny difference in the birth Moon's measured position that compounds across the full 120 year cycle, and a different classical year length the two engines use to lengthen each period (we use 365.25 days, Drik uses the sidereal year of about 365.256 days).
Cross-check these values against Drik Panchang for the same date, time, and place.
Kaal Sarp Dosha is a chart pattern where all seven traditional planets fall between Rahu and Ketu, the two shadow points opposite each other in the zodiac. This calculator checks whether your chart shows this pattern and, if it does, reports the traditional type and name associated with it.
Your birth details are sent to VedicShala's astrology calculation provider, which computes the positions of all nine planets, including Rahu and Ketu, and checks whether the seven traditional planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn) all fall on one side of the Rahu-Ketu axis. If they do, the pattern is present, and the calculation provider also identifies a traditional type and name for the specific configuration, based on which houses Rahu and Ketu occupy. If the planets are spread across both sides of the axis, the pattern is not present.
This is a well-documented chart pattern that traditional astrology has read for centuries. It is a traditional factor to understand and plan around, not a curse, and this calculator teaches it the same way it teaches every other chart factor: state the placement plainly, explain what the tradition says, and leave the interpretation to you.
If every planet from the Sun through Saturn falls between Rahu at, say, 40 degrees and Ketu at 220 degrees, moving in one consistent direction around the zodiac, the pattern is present, and the calculator additionally names the specific traditional type based on which houses Rahu and Ketu occupy in your chart.
Enter your date, time, and place of birth into the form above. Your birth details are sent to our astrology calculation provider so it can compute your result; the provider discards those details afterward and we do not store them unless you choose to save the result to a free VedicShala account.
This calculator reports one specific traditional configuration, not a comprehensive assessment of your chart's overall balance. Different traditional sources describe the various Kaal Sarp types somewhat differently, so treat the specific type name as one traditional reference, and treat the presence or absence of the pattern itself as a fact to understand about your chart, not something to act on out of concern.
